We empower makers to build AI assistants that everyone can use

Rasa is the leading open source machine learning toolkit that lets developers expand bots beyond answering simple questions. Our open source Rasa Stack enables thousands of developers worldwide from startups to Fortune 500 to build in-house conversational AI (e.g. sophisticated chatbots and voice assistants) without hiring a big research team.

Rasa Platform, a paid product, makes it simpler to train our machine learning models across multiple enterprise functions, allowing for faster iteration cycles.

To date, we've had more than 100 people contribute to Rasa Stack. Our core team is a tight-knit, fast-moving team of researchers, engineers, designers and product people, with extensive experience in machine learning, natural language processing and rapid product design.
